MAGAZINE ATTACHMENT FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 764,243, dated July 5,1904.

Application filed March 7, 1904. Serial No. 197,029. (No model.)

To all w/zmn zit nuty concern:

Be it known that I, THOMAS C. J OHNSON, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Wrench Attachments for Tubular Magazines for Guns; and Ido hereby declare the following, when taken in connection with theaccompanying drawings and the figures of reference marked thereon,

to be a full, clear, and exact description of the same, and which saiddrawings constitute part of this specification, and represent, in

Figure 1, a broken view, partly in side elevation and partly in verticallongitudinal section, of a gun the tubular magazine of which is providedwith one form which my improved wrench attachment may assume; Fig. 2, adetached broken view of the front end of the magazine, which is shown invertical section with the wrench attachment in elevation and in itsoperative position; Fig. 3, a View in front elevation of the magazineand wrench attachment, which latter is shown in its operative position;Fig. 4, a detached View, in side elevation, of the wrench attachment;Fig. 5, a detached reverse plan view thereof; Fig. 6, a detached view ofthe wrench attachment, partly in central longitudinal section and partlyin elevation; Fig. 7, a detached view of the wrench attachment in frontelevation.

My invention relates to an improvement in attachments for use inscrewing tubular magazines into and unscrewing them from gunframes, theobject being to permanently provide tubular magazine-guns with simpleand convenient means for removing and replacing their magazine asrequired.

With these ends in view my invention consists in the combination, withthe front end of a tubular magazine, of a wrench attachment mounted inthe said end of the magazine for endwise movement therein in linetherewith, whereby it may be normally retired thereinto and whenrequired for use pulled out therefrom and swung on its inner end as on apivot and brought into position at a right angle to the magazine andthen used as a wrench for turning the magazine one way or the other.

My invention further consists in a wrench attachment for tubularmagazines having certain details of construction, as will be hereinafterdescribed, and pointed out in the claims. In carrying out my inventionas herein shown-I employ a wrench attachment in the form. as may besaid, of a spanner-wrench. This consists of a straight shank 2,furnished at its outer end with a hollow operating-button 3 and at itsinner end withatrunnion-like arm 4:, arranged at a right angle to it,round in cross-section, and formed with a transverse perforation 5 forthe reception of a retaining pin 6. At its outer end the shank is formedwith a locking-shoulder 7, which is placed directly opposite aretaining-spring 8, located in part in a longitudinal slot 9, formed inthe shank, the outer end of the spring extending into a hole 10, formedin the button 3, and its inner end being bent at a right angle andinserted into a hole 11, leading out of the bottom of the recess 9. Alocking-notch 7 isformed between the shoulder 7 and the innenna; face ofthe button 3, the shoulder and button..

holding the attachment against endwise movement in either direction whenthe wrench is not in use. Midway of its length and upon its under facethe shank 2 is providedwith a clutch'or spanner pin 12, forming anoperating projection.

As shown, the wrench is mounted for free endwise movement in a cap 13,having at its inner end an externally-threaded sleeve 14, adapting it tobe screwed into the internallythreaded front end of the tubular magazine15, which it closes and for which it forms a finish. The said cap 13 isformed with a central opening 16 for the reception of the wrenchattachment, which is movable freely endwise back and forth through it,the retaining-pin 6 being passed through the perforation 5 in. thetrunnion 4 after the trunnion end of the attachment has been passedthrough the hole 16 in the cap. The button 3 then prevents the wrenchattachment from being disconnected from the magazine when the attachmentis moved inward, while the pin 6 prevents the attachment from beingdisconnected from the magazine when it is moved outward. Spannerpinholes 17 formed in the face of the cap 13, provide for screwing the capinto and unscrewing it from the magazine by means of an ordinary spannerwrench, which is not shown.

The front end of the magazine is furnished with an integral or fixed tip18 in the form of a radial flange, the front face of which is furnishedwith spanner or clutch pin holes 19 for the reception of the spanner orclutch pin 12 of the wrench attachment, the rear face of the tip 18being formed with an annular groove 20 for the reception of a tenon 21,located upon the forward end of the forestoek 22, the rear end of whichis formed with a tenon 23, entering a groove 24, formed in the frontface of the lower portion of the gun-frame 25, which is furnished withan internally-threaded socket 26 for the reception of the threaded rearend of the magazine 15. The magazine is also formed with an integralstop-shoulder 27, engaged by a buffer 28, engaged with the forward edgeof a guidering 29, depending from the reeoiling barrel 30 and having itsrear edge engaged by the forward end of the barrel-closing spring 31,encircling the magazine and abutted at its rear end on the front face ofthe lower portion of the gun-frame.

Normally the Wrench attachment is retired into and housed in the frontend of the magazine, at which'time its longitudinal axis is parallelwith the longitudinal axis thereof, as shown in Fig. 1, the attachmentbeing held in this position by its retaining-spring 9, which engageswith the wall of the opening 16 and forces, the attachment in theopposite direction, so as to cause its locking-notch 7 to be engagedwith the Wall of the opening 16 at a point just opposite the pointengaged by the said spring, whereby the attachment is firmly held inplace. When, however, it is desired to use the attachment, the button ispushed, against the tension of the spring 8,, the position of which isalways disclosed by the hole 10 in the button. This sidewise movement ofthe attachment enables the shoulder 7 to be cleared from the wall of theOpening 16, through which the attachment may now be pulled endwise andoutward by its button until its arm 4 is engaged with the inner face ofthe cap 13, after which the attachment is swung at a right angle to theaxis of the barrel, as shown in Figs. 2 and 3, turning upon itstrunnion-like arm 1 as upon a pivot. When in this position, theattachment is prevented from becoming detached by the retaining-pin,which engages with the inner face of the cap 13. The attachment may nowbe swung in the plane of the cap 13 and tip 18, turning very freely uponthe circular portion of the arm 4:. Now by carrying the attachmentslightly outward away from the cap 13 and tip 18 its spanner-pin 21 maybe engaged with any one of the spanner-pin holes 19 and readily shiftedfrom one hole to another in the usual way of using a commonspanner-wrench. When so engaged with the tip 18, the attachmentconstitutes a powerful wrench for screwing the magazine into the gunframe and unscrewing it therefrom. When this has been done, it is asimple matter to swing the attachment out into alinement with themagazine and then push it inwardly by endwise pressure upon its button 3until the spring 8 acts to shift it sidewise, and so look it in placeinits retired or housed position, as shown in Fig. 1.

It is apparent that in carrying out my invention some changes from theconstruction herein shown and described may be made. I would thereforehave it understood that I do not limit myself thereto, but hold myselfat liberty to make such departures therefrom as fairly fall within thespirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the front end of a tubular magazine, of a wrenchlil(e attachment mounted for endwise movement therein in line therewith.

2. The combination with the front end of a tubular magazine, of a wrenchattachment mounted for endwise movementtherein in line therewith andprovided at its inner end with a trunnion-like arm on which it turns asupon a pivot when extended and adapted at its outer end to be graspedand drawn out into its extended position.

3. The combination with the front end of a tubular magazine, of a Wrenchattachment mounted for endwise movement therein in line therewith andprovided at its inner end with a trunnion-like arm on which it is turnedas upon a pivot when in its operating position and at its outer end withan operating-button, and means for retaining it in its retired positionin which it is housed within the front end of the magazine.

4. The combination with the front end of a tubular magazine, of a wrenchattachment mounted for endwise movement therein in line therewith andadapted at its ends to prevent its being disconnected therefrom andprovided with a projection for operative engagement with the magazinewhen in its extended and operating position.

5. The combination with the front end of a tubular magazine, of a wrenchattachment mounted for endwise movement in line there- 'with, andprovided at its inner end with 'a trunnion-like arm, at its outer endwith an operating-button, with a locking-spring for holding it 1n itsretired position in which it is IIO angle to the magazine to be engagedtherewith for screwing and unscrewing the same. 7. The combination witha tubular magazine formed at its front end with a collar-like tip, of aWrench attachment mounted in the front end of the magazine for endwisemovement therein in line therewith and adapted When extended and turneddownward at a right angle to the magazine to be engaged with the saidtip for turning the magazine in either direction.

In testimony whereof I have signed this specification in'the presence oftwo subscrib- 1ng Witnesses.
